Gluconobacter oxydans DSM 2343 is known to catalyze the oxidation of glucose to gluconic acid, and subsequently, to 2-keto-D-gluconic acid (2-KGA) and 5-keto-D-gluconic acid (5-KGA), by membrane-bound and soluble dehydrogenases. In G. oxydans MF1, in which the membrane-bound gluconate-2-dehydrogenase complex

We isolated thermotolerant Gluconobacter strains that are able to produce 5-keto-d-gluconic acid (5KGA) at 37 degrees C, a temperature at which regular mesophilic 5KGA-producing strains showed much less growth and 5KGA production. The thermotolerant strains produced 2KGA as the major

The chromosomal locus NP_636946 of Xanthomonas campestris DSM 3586 (ATCC 33913) which was earlier presumed to encode a quinoprotein glucose dehydrogenase has been cloned, expressed in Escherichia coli and the recombinant enzyme has been characterised. It was found to have

Gluconacetobacter diazotrophicus an endophytic diazotroph also encountered as rhizosphere bacterium is reported to possess different plant growth promoting characteristics. In this study, we assessed the zinc solubilizing potential of G. diazotrophicus under in vitro conditions with different Zn compounds using
